Came up with this an hour ago. All the standard pawns are replaced with standard rooks and the rooks with pawns. Black kept winning(!), first with a king-and-queen mate and then a much faster queen-and-bishop mate, so I have given the computer three minutes to think about every move. This computer gaming program will be the end of me.
Black wins again with 29. ... Qf7#. White sacrificed its Queen on move 7 when it could have instead easily used a Knight or Rook to take back. I can't tell if I broke the engine with too many available Rook moves or if the game is just somehow massively skewed for Black.
Zillions' weird notation below:
- Rook a2 x a7
1...Rook h7 x h2 - Rook f2 x f7
2...King e8 x f7 - Rook a7 x b7
3...Bishop c8 x b7 - Rook g2 x h2
4...Rook g7 x g1 - Rook h2 x h8
5...Bishop b7 - a6 - Knight b1 - c3
6...Rook e7 x e2 - Queen d1 x e2
7...Bishop a6 x e2 - Rook d2 x e2
8...Rook c7 x c3 - Rook e2 - f2
9...King f7 - g7 - Rook h8 x g8
10...King g7 x g8 - Rook c2 x c3
11...Bishop f8 - g7 - Rook b2 - b3
12...Bishop g7 x c3 - Rook b3 x c3
13...Rook d7 - e7 - Rook c3 - e3
14...Queen d8 - a5 - King e1 - e2
15...Queen a5 - b5 - King e2 - d2
16...Queen b5 - b4 - King d2 - d3
17...Queen b4 - b3 - King d3 - e2
18...Queen b3 - c4 - King e2 - d2
19...Rook e7 - d7 - Rook e3 - d3
20...Rook d7 x d3 - Bishop f1 x d3
21...Queen c4 x c1 - King d2 - e2
22...Queen c1 - d1 - King e2 - e3
